Business Description, Basis of Presentation and Significant Accounting Policies


1.	Business Description, Basis of Presentation and Significant Accounting Policies

Business Description:

ClearOne, Inc. and its subsidiaries (collectively, “ClearOne” or the “Company”) are a global company that designs, develops and sells conferencing, collaboration, streaming and digital signage solutions for audio and visual communications. The performance and simplicity of its advanced comprehensive solutions offer unprecedented levels of functionality, reliability and scalability.

Basis of Presentation:

The fiscal year for ClearOne is the 12 months ending on December 31^st. The consolidated financial statements include the accounts of ClearOne and its subsidiaries. All significant inter-company accounts and transactions have been eliminated.

These accompanying interim condensed consolidated financial statements for the three months ended March 31, 2015 and 2014, respectively, have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and are not audited. Certain information and footnote disclosures that are usually included in financial statements prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) have been either condensed or omitted in accordance with SEC rules and regulations. The accompanying consolidated financial statements contain all adjustments, consisting of normal recurring accruals, necessary for a fair presentation of our financial position as of March 31, 2015 and December 31, 2014, the results of operations for the three months ended March 31, 2015 and 2014, and the statements of cash flows for the three months ended March 31, 2015 and 2014. The results of operations for the three months ended March 31, 2015 and 2014 are not necessarily indicative of the results for a full-year period. These interim condensed consolidated financial statements should be read in conjunction with the financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2014 filed with the SEC.

Significant Accounting Policies:

The significant accounting policies were described in Note 1 to the audited consolidated financial statements included in the Company’s annual report on Form 10-K for the year ended December 31, 2014. There have been no changes to these policies during the three months ended March 31, 2015 that are of significance or potential significance to the Company.

Recent Accounting Pronouncements:

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), requiring an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The updated standard will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective and permits the use of either a full retrospective or retrospective with cumulative effect transition method. Early adoption is not permitted. The updated standard becomes effective for the Company on January 1, 2017. The Company has not yet selected a transition method and is currently evaluating the effect that the updated standard will have on the consolidated financial statements.

Business Combination

Acquisition of Sabine

On March 7, 2014, the Company completed the acquisition of Sabine, Inc. ("Sabine") through a stock purchase agreement ("SPA"). Sabine manufactures, designs and sells Sacom professional wireless microphone systems for live and installed audio. It also makes FBX Feedback Exterminator for reliable automatic feedback control. With the addition of Sabine, ClearOne will have reliable and exclusive access to the wireless microphones that are a critical component of ClearOne’s complete microphone portfolio.

Pursuant to the SPA, the Company (i) paid initial consideration of $8,141 in cash, (ii) accrued for possible additional earn-out payments over the next two years, estimated to be $657, and (iii) issued 150,000 shares of restricted common stock of the Company, valued at $1,679 (determined on the basis of the closing market price of the Company's stock on the acquisition date). The purchase price was paid out of cash on hand. The SPA contains representations, warranties and indemnifications customary for a transaction of this type.

The following table summarizes the consideration paid for the acquisition:



	Consideration
Cash	$	8,141
Common stock	1,679
Contingent consideration	657
Total	$	10,477

The fair values of Sabine assets acquired and liabilities assumed are based on the information that was available during the measurement period of twelve months from the date of acquisition. The fair value of identified assets and liabilities acquired and goodwill is as follows:



	Fair value
Cash	$	125
Accounts receivable	255
Inventories	844
Prepaid and other	105
Intangibles	3,970
Property, plant and equipment	292
Other long-term assets	11
Goodwill	5,510
Deferred tax asset	245
Trade accounts payable	(420		)
Accrued liabilities	(405		)
Stock registration costs	(55		)
Total	$	10,477

The goodwill of $5,510 related to the acquisition of Sabine is composed of expected synergies in utilizing Sabine technology in ClearOne product offerings, reduction in future combined research and development expenses, and intangible assets including acquired workforce that do not qualify for separate recognition. The goodwill balance of $5,510 related to the acquisition of Sabine is expected to be deductible for tax purposes.

Supplemental Pro Forma Information:

1) Revenue and net loss from the Sabine business from March 8, 2014 to March 31, 2014 were $84 and $163 respectively.

2) Revenue and earnings of the combined entity as though the business combination occurred as of January 1, 2014 were as follows:



	Three months ended March 31,
	2015		2014
Revenue	$	13,586	$	12,977
Earnings	1,272		244
Basic earnings per common share	$	0.14	$	0.03
Diluted earnings per common share	$	0.13	$	0.03

3) There were no material, nonrecurring pro forma adjustments directly attributable to the acquisition included in this Supplemental Pro Forma Information.

Acquisition of Spontania Business of Spain-based Dialcom Networks, S.L.

On April 1, 2014 ClearOne, Inc. closed on the acquisition of the Spontania business of Spain-based Dialcom Networks, S.L. The Spontania cloud-based service empowers customers to deploy HD video conferencing, web collaboration, and more with equipment most businesses have and use every day - video-conferencing endpoints, desktops, laptops, web browsers, tablets, and smartphones. With Spontania there is no hardware investment and the service operates off of a reservation-less model, enabling on-demand video communications from virtually anywhere, anytime, with anyone on any device.

The aggregate purchase price under the terms of the transaction was approximately €3.66 million in cash (approximately US$5.1 million ), after certain closing adjustments. ClearOne did not assume any debt or cash. The cash purchase price was paid out of cash on hand. The addition of this technology was an integral part of the company’s strategy to build an all-inclusive video collaboration portfolio.

The fair value of identified assets and liabilities acquired from the Spontania acquisition was as follows:



	Fair value
Intangibles	$	1,335
Property and equipment	47
Goodwill	3,741
Accrued liabilities	(71		)
Total	$	5,052

The goodwill of $3,741 relates to the acquisition of Spontania cloud-based technology and intangible assets including acquired workforce that does not qualify for separate recognition. The goodwill of $3,741 from the Spontania acquisition is expected to be deductible for tax purposes.

Supplemental Pro Forma Information:

Revenue and earnings of the combined entity as though the business combination occurred as of January 1, 2014 is not available. The Spontania business was part of a business unit of Dialcom Networks, S.L., and thus separate stand-alone financial information for Spontania is not available.

Acquisition Expenses:

During the period ended March 31, 2015, the company incurred $70 in total acquisition related expenses for the Sabine and Spontania acquisitions, all of which are categorized under general and administrative expenses in the Consolidated Statement of Operations.

Retroactive Restatement:

Following the completion of the valuation process for the acquisition of Sabine we reported intangible amortization to reflect the final adjusted values on Form 10-K for the year ended December 31, 2014. For the quarter ended March 31, 2015 we reported amortization based on the final intangible items. For the comparative quarter ended March 31, 2014 we have restated net income to reflect the inclusion of the revised amortization applicable to that period. Net income changed from $490 originally reported for the three months ended March 31, 2014 to $485. The reported retained earnings balance of $29,482 at March 31, 2014 under the restatement would be $29,477. The restatement did not result in a reportable change to earnings per share for the period.

Investments, Debt and Equity Securities [Abstract]

Marketable Securities

The Company has classified its marketable securities as available-for-sale securities. These securities are carried at estimated fair value with unrealized holding gains and losses included in accumulated other comprehensive income/loss in stockholders' equity until realized. Gains and losses on marketable security transactions are reported on the specific-identification method. Dividend and interest income are recognized when earned.

The amortized cost, gross unrealized holding gains, gross unrealized holding losses, and fair value for available-for-sale securities by major security type and class of security at March 31, 2015 and December 31, 2014 were as follows:



			Amortized cost		Gross unrealized holding gains		Gross unrealized holding losses			Estimated fair value
March 31, 2015
	Available-for-sale securities:
		Corporate bonds and notes	$	19,220	$	162	$	(48	)	$	19,334

Maturities of marketable securities classified as available-for-sale securities were as follows at March 31, 2015:



		Amortized cost		Estimated fair value
March 31, 2015
	Due within one year	$	7,327	$	7,314
	Due after one year through five years	17,611		17,771
	Due after five years through ten years	361		362
	Total available-for-sale securities	$	25,299	$	25,447

Debt securities in an unrealized loss position as of March 31, 2015 were not deemed impaired at acquisition and subsequent declines in fair value are not deemed attributed to declines in credit quality. Management believes that it is more likely than not that the securities will receive a full recovery of par value. The available-for-sale marketable securities in a gross unrealized loss position as of March 31, 2015 are summarized as follows:

Fair Value Disclosures [Abstract]

Fair Value Measurements

The fair value of the Company's financial instruments reflects the amounts that the Company estimates it will receive in connection with the sale of an asset or pay in connection with the transfer of a liability in an orderly transaction between market participants at the measurement date (exit price). The fair value hierarchy prioritizes the use of inputs used in valuation techniques into the following three levels:

Level 1 - Quoted prices in active markets for identical assets and liabilities.

Level 2 - Observable inputs other than quoted prices in active markets for identical assets and liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. This category generally includes U.S. Government and agency securities; municipal securities; mutual funds and securities sold and not yet settled.

Level 3 - Unobservable inputs.

The substantial majority of the Company’s financial instruments are valued using quoted prices in active markets or based on other observable inputs. The following table sets forth the fair value of the financial instruments re-measured by the Company as of March 31, 2015 and December 31, 2014:

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company's forecasted effective tax rate at March 31, 2015 is 35.8%, a 3.8% increase from the 32.0% effective tax rate recorded at December 31, 2014. The forecasted effective tax rate of 35.8% excludes jurisdictions for which no benefit from forecasted current year losses is anticipated. Including losses from such jurisdictions results in a forecasted effective tax rate of 36.1%. Our forecasted effective tax rate could fluctuate significantly on a quarterly basis and could change, to the extent that earnings in countries with tax rates that differ from that of the U.S. differ, from amounts anticipated at March 31, 2015. After discrete tax expense of $2, the effective tax rate for the quarter ended March 31, 2015 is 36.5%. The discrete tax expense is primarily attributable to interest and penalties related to unrecognized tax benefits.
